Spot Supply Hydraulic MONTABERT Rock Drills HC50

Product of MONTABERT Rock Drills

Montabert hydraulic rock drill is a long rock breaking machine and rig design and manufacturing experience crystallization.
In-depth knowledge of the shock wave theory and the transmission mechanism of our engineers pioneered the development of new concepts and progressive hydraulic damping battle can wait.
Our close relationship between manufacturing and engineering, ultra-modern machining tools, and the precision heat treatment workshop of our St. Priest factory are some of the factors that enable us to provide hydraulic rock drills that are recognized as the world's leading.

Features of MONTABERT Rock Drills

1

 Energy recovery valve
This valve allows the piston rebound energy to be utilized for the next blow,
giving a definite advantage to the HC series drifters:
• Better efficiency
• No internal peak of pressure source of cavitation
• Best drifter protection
2

 Progressive blow energy
The unique design of the piston generates a perfect, long
trapezoidal-shaped shock wave:
• Better energy transmission to the bits
• Minimum stress into the drill string
• Better bit penetration

3

Hydraulic dampening system
The action of the dampening piston not only absorbs the lost
part of reflected energy but also ensures a constant thrust onto the tools:
• Optimum shock wave transmission
• Protection of the drifter and tools
• Reduced vibrations
4
Hydraulic reserve percussion
The optimal hydraulic reverse percussion system ensures a real back hammering:
• Tool extraction in fractured ground
• No rods left in the hole
Straight holes drilling
• When associated with Montabert drilling controls
